7 Claims.

This invention relates to portable ash containers for use in an ashremoval system of a domestic heating furnace to `receive `the'ashesAfrom an Aash conveyor of the Worm feed type.

One oi theprincipal objects of the invention 'is to provide such an ashcontainer having van ash receiving opening 'therein for-receiving'froznbelow Athe ashes vdischarged upwardly by the conveyor which is ofsimple`andlightweight construe-- tion for economical manufacture and readyhandling in use and wherein the ash vreceiving opening is arranged lforsuch cooperative actions/ith an upwardly projecting discharge tube fromthe conveyor as to eliminate the 'necessity of a valve or other closurefor theash'receiving opening during removal `and "dumping of thecontainer.

Another-object is to providesuch an ash container 'hav-ing therein anVashrreceiving tube -eX- tending upwardly from the ash yreceivingopening inthe vbottomv of the Container and adapted -for mounting invtelescopingrelation upon ythe -up- Wardly projecting dischargetube fromthe conveyor to `receive vashesl therefromand 'to discharge the ashesinto the container at a position -near the topthereof thus Veliminatingthenecessity of fa valve or othermovable closure for the bottom of thecontainer.

' It is also an object yof ft-hefinvention te provide such lanashcontainer Iwherein'the upper ends of the discharge tube `of 1theconveyor and "the yash receiving tube in thecontainercooperate to form asealed-connectionsupporting ftheoontainerfrom the top ofthedischarge-.tubelin position tofreoeive ashes from the conveyor.

-The Acontainer .30 is adapted for vremovable mounting on the `ashconveyor .I-i ,.to receive :the ashes from 4funnel r2`l,1thiscontainerbeing porta.- ble to facilitate ready-carryineaway.andrdumpingof the ashes. It is generally ,rectangular in horizontal section, and itis provided @Vith :asuitable :top-3l 4sealed ,against ya ,gasket 132y:to ,pref ,vent l escape of-ashes VVor `dust ,therefrom. :The top :.32iis-provided with a handle and tivo :handles 134er@ fastenedtolthlefendsforuse 3 handling the container. The bottom 35 of thecontainer is provided with an ash receiving opening 36 symmetricallylocated at the center thereof and of sufiicient diameter to receive theflared ring or collar portion 25 of funnel 2l] therethrough.

A tube 40 open at both ends thereof and of substantially the same innerdiameter as the ash receiving opening 36 has its lower end secured tothe bottom of the container in concentric relation with the opening 36.As shown in Fig. 4, the lower end of tube is flanged at 4l to facilitatewelding or bolting to the bottom of the container, and the tube extendsupwardly within the container to a position spaced well above thecontainer bottom 35. A ring or collar 42 is welded or otherwise securedaround the upper end of the tube 40, and this ring includes an annularflange extending inwardly of tube 40.

The ring 42 cooperates with ring 25 to support the tube 4I and thecontainer on funnel 20. Referring to Fig. 4, the upper part of the ring42 includes an outer portion 44 which is tapered upwardly and an innerportion 45 which is tapered downwardly and extends radially inwardlywith respect to the tube to a sufficient distance to overlap the upperend of the ring 25. This inner portion 45 of ring 42 is tapered atsubstantially the same angle as the portion 26 of the ring 25, so thatthe adjacent surfaces of these tapered or flared ring portions engage insealing relation when the tube and funnel are in substantially fullytelescoped relation, and thus cooperate to support the container and thetube 40 on the top of funnel 20. The outer ends of the ange 22 areturned upwardly at 4t to aid in positioning the container on the funnel.

It will be seen that with this construction of the container 30 andfunnel 26, the ashes fed upwardly from the conveyor Il into the funnelwill spill over the top of the tube 4f! and ring 42 and fall down intothe interior of the container, the discharge of ashes from the funnelinto the container thus taking place near the top of the container. Whenthe ashes have accumulated to a sufiicient extent to make dumping of thecontainer advisable, it can be simply lifted up by means of the handles34 and carried away for dumping. Since the upper or discharge end of thetube 40 is near the top of the container, there will be no danger ofaccumulated ashes spilling out while the container is being moved, andaccordingly it is unnecessary to provide a valve or other closure forthe discharge opening 36. The rectangular configuration of the containeris helpful if the ashes have accumulated above the top of the funnel,since such excess accumulation can be readily pushed or brushed out intothe space at either end of the container before it is lifted. Thiscontainer can thus be made of relatively light sheet stock, and it istherefore economical to produce and easy to handle in use.

While the form of apparatus herein described constitutes a preferredembodiment of the invention, it is to be understood that the inventionis not limited to this precise form of apparatus, and that changes maybe made therein without departing from the scope of the invention whichis defined in the appended claims.
